Furthermore the AP exam environment, IMO, varied by the school giving it. I could have easily stored formulas in my calculator (for the calculator section), I could have easily colluded with classmates, and if my teachers wanted to, they could've easily given me the answers. It was a bit of a joke really. Multiple phones went off during the exam, no penalties were given (which I agree is the right approach, but it does say something about the exam itself).
The prestige of the AP program and the experience of taking a number of AP courses has contributed to my declining respect for our higher education system really.
